2 Claims.

The invention relates to building construction and more particularly to a building wall structure.

The main object of the invention is to provide means for anchoring together hollow building blocks, such as cement or cinder blocks, in wall formation whereby the blocks are firmly held together and to the foundation.

A further object of the invention is to provide a wall construction in which the block anchoring means is also associated with means for attaching inside and outside siding to the block wall.

The invention further consists in the several features hereinafter set forth `and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. l is a perspective view of a wall structure embodying the invention, parts being broken away and parts being shown in section;

Fig. 2 is a perspective View of the block anchoring means and siding ties;

Fig. 3 is a vertical sectional view through a portion of the wall;

Fig. 4 is an enlarged perspective view of a part of the wall anchor.

Referring to the drawings, the numeral 5 designates the foundation footing of concrete or other suitable material upon which the blocks 6 forming the wall are laid. The blocks B may be blocks of cast cement or cinder concrete and are usually provided with spaced vertically disposed openings or passages and an end recess 8. rlhe invention relates to a means for anchoring these blocks in the form of a wall to the foundation and to means for connecting adjoining blocks together.

As shown in Fig. l, the blocks are laid upon the footing 5 so as to form side walls, the blocks being placed one above the other as the wall is built up with adjacent blocks of each wall layer abutting or disposed in close spaced relation to each other.

The numeral 9 designates an anchor plate having end anges Ill. The length of the plate is such that the flanges I@ engage over the sides of openings l in adjacent blocks, so that the plates provide means for preventing lateral movement of the blocks relative to each other. Each plate is provided with a centrally located opening II punched out therefrom to provide projecting ears or stops I2. The openings I I aline with the end recesses 8 of the blocks.

For anchoring the blocks, tie means are provided between the foundation and the plates IIJ on the first course of the wall and between the plates Ill of each course. Referring to Fig. 3, a hooked bolt I3 has a portion of its shank and its nut I4 anchored in the concrete footing 5. A tie wire I5 of suitable metal, preferably having its ends connected together, forms an elongated loop Whose lower end I6 is hooked over the hooked end of the bolt I3 and whose upper, preferably looped, end I'i' is passed through the opening II of an anchor plate 9 disposed above the bolt I3 and resting on the tops of adjacent blocks 6. For setting the tie, a small metal pin I8 may be placed between the spaced strands of the loop, as shown in Fig. 4, and then another pin I9 may be placed in the end of the loop and used to turn or twist this end of the loop so as to bind the pin I8 firmly against the plate I0 and at the same time tension that portion of the loop extending from hook I3 to the plate. In the twisting process the pin I8 is prevented from rotating by engagement with the projections I2 on the plate lli. The result of this twisting of the loop is shown in Figs. 2 and 3. In this way the first course of the blocks 6 forming the wall is rmly connected to the foundation footing 5.

The second and subsequent courses of the wall are formed by tying adjacent blocks of each course together and to the footing ties. For this purpose a looped wire tie 20 similar to the footing tie loop has its lower looped end 2l hooked over the pin I9 of the foundation tie and its upper looped end is as before inserted through the opening II of an anchor plate I resting on the tops of blocks 6 of the second course, and then the upper looped end is twisted down against a pin 22 inserted between the strands of the loop by another pin 23 inserted at the upper end of the loop. Subsequent courses of blocks are similarly connected to lower courses by wire ties that connect the twisted end of a lower tie with the plate ID of an upper course.

The wall siding may also be connected to the wall without the necessity of using nails by wire ties that bind the siding to the wall and connect with the anchor plates I0.

As shown, each anchor .plate I0 has holes 24 spaced from its side edges. A looped wire 25 is run through each hole 2li and out through the tops of each course of blocks E or in some instances it may be run through the space between blocks of adjacent courses where four blocks adjoin each other. For the exterior siding the looped wire 25 is passed through a hole 25 in the insulation board 2'! and through an alined hole 28 in the upper portion of the siding proper 29. The looped wire 25 is then drawn taut to tie the siding to the block wall by the same method as previously described by using a pin 30 and a pin 3| similar to the pins 22 and 23, the end 32 of the loop being twisted against the pin 30, as shown in Fig. 3, and then a part of the twisted end 32 with the pin 3| therein may be cut off and the rest of this end bent down against the sidingand be covered by the next outer siding course. A similar procedure is followed for anchoring the inside siding to the wall. As shown, this inside siding is formed of insulation board 33 and the siding proper 34. The looped Wire 25 on the inner side of the plate is brought through spaced parts of the blocks 6 and passed through alined holes 35 and 36 in this inside siding and then drawn taut and twisted by the use of pins 31 and 38 in the same Way as the outer siding is connected to the wall and then a portion of the twisted end 39 with the pin 38 may be cut off and the rest of said end bent down against the siding.

The form of wall construction above described obviates the use of mortar joints and nails. As in known constructions, long tie rods (not shown) are anchored at one end in the foundation footings and extending up to the top of the wall and bolted to top plates may be used if further wall reinforcement is necessary.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention is:

1. In a wall structure having a foundation footing and superimposed courses of building blocks, each block having an end recess and passages, the combination of apertured metal anchor plates mounted on the tops of adjacent blocks of each course of the wall and overlying said recesses and :provided with means engaging the sides of passages of adjacent blocks for preventing longitudinal movement of adjacent blocks relative to each other, looped tire wires having their -upper ends extending through the apertures of said anchor plates, each of said wires carrying a pin straddling the aperture of a plate and held against the same by twisted portions of the upper looped end of the wire to anchor the Wire to the plate, means connecting the upper and lower ends of the tie wires of adjacent courses together 4 between the plates overlying the blocks of adjacent courses to anchor said courses together, and connections for the lower looped ends of the tie wires of the first course with the foundation footing.

2. For a wall structure having a foundation footing and superimposed courses of cored building blocks providing passages, a wall anchorage for preventing longitudinal movement and vertical movement of the blocks forming the wall comprising the combination of a series of apertured metal anchor plates overlying the tops of adjacent blocks and having flanges engageable with the sides of passages of adjacent blocks to prevent longitudinal movement of adjacent blocks of a course relative to each other, a series of looped tie wires, tie pins and anchoringl pins for vertically connecting the plates of adjacent courses together, each of said tie wires extending through the aperture in its associated plate and held in twisted relation with one of said anchor pins against this plate with its twisted end extending above said plate and a looped portion extending below said plate, means on each plate for holding its anchor pin against turning, said tie pins connecting the twisted end portion of the tie wire above the plate with the looped end of a tie Wire depending from a plate overlying blocks in the next course, Aand an anchor connection between the depending portion of each tie wire for the rst course with the foundation footing.
